<p>In a heat exchanger for condensing a gas by passage through vertically spaced heat exchange tubes, flooding of the lower tubes is prevented. A return flow header includes nested baffles which define isolated flow channels connecting one or more predetermined upper heat exchange tubes with a single predetermined lower heat exchange tube. This prevents the condensed liquid in the header from completely filling the lowermost tube or tubes. Removable plugs or plates permit access to the inside of the heat exchange tubes for cleaning.</p> |
